Sorry I try to explain it better.
I was thinking to a gcc plugin (or potentially something else) that
given a C file produce the libgccjit code necessary to fill a context
with what is in the source file.

Say you want then to use it to solve the code duplication we have seen for
structure definitions. You could use a two step compilation strategy:
- first with the plugin you create the libgccjit code you need to define
  in the jitter the structures.
- second you include it in your codebase and you do your usual compilation.

As I sayid it could also potentially compile not just structs and unions
but also the whole C subset supported.
